The spring undergoes a change in potential energy of
1/2 k (2.9 m)² - 1/2 k (1.4 m)² = 87 J
Solve for k :
k ((2.9 m)² - (1.4 m)²) = 174 J
k = (174 J) / ((2.9 m)² - (1.4 m)²)

What are the equations of the asymptotes of the hyperbola? (y+4)236−(x−6)249=1 enter your answer in point-slope form by filling in the boxes. Enter the slope as a simplified fraction.
The point slope form of the asymptote of the hyperbola is; y - 4 = ±(6/7)(x - 6)
We are given the equation of the hyperbola as;[(y + 4)²/36] - [(x - 6)²/49] = 1
We can rewrite this equation as;[(y + 1)²/6²] - [(x - 6)²/7²] = 1
The general equation form of hyperbola is;[(y - k)²/a²] - [(x - h)²/b²] = 1
Comparing this general form to our given equation we can see that;k = -4
h = 6
a = 6
b = 7
Now the equation of the asymptote of a hyperbola follows the general formula;y = ±[a(x - h)/b] + k
Plugging in the relevant values gives us;y = ±(6/7)(x - 6) - 4
>> y - 4 = ±(6/7)(x - 6)

English nobles resisted peasant demands such as those described in the passage because agricultural labor in many parts of fourteenth-century afro-eurasia had become scarce as a result of which of the following developments?.
Answer: Significant increase in mortality due to the spread of epidemic diseases.
Explanation:
During the 14th century, many parts of Europe and Asia were completely ravaged by an epidemic plague called The Black Death. It was a form of bubonic plague caused by rats infected by bacteria.
More than half of the population of Europe was killed due to his plague, which immediately creates a shortage of labor. Shortage of labor, including agricultural ones, immediately meant that the living ones would receive a higher wage, to the consternation of the landowners who pushes for legislation that would return the status quo to how it was prior to the Black Death. This enrages the peasants who worked for them; manifesting in several revolts from May to November 1380.

A scale factor of one-third is used to make a reduction of the original triangle. Original triangle reduced triangle height 12 base 24 what is the base of the reduced triangle? 4 8 9 21.
Answer:
B - 8
Explanation:
The linear scale factor is used to reduce or enhance the size of the original measures. The base of the reduced triangle is 8. Thus, option b is correct.
What is a linear scale factor?The linear scale factor is the reduction or the enlargement of the size like the width, height, base, length, etc. of the geometrical shape.
Given,
The height of the original triangle = 12
The base of the original triangle = 24
The linear scale factor reduces the original size by 1/3 factor.
The 1/3 factor of the base will be = 24 ÷ 3 = 8

You wish to earn a return of 13% on each of two stocks, x and y. Stock x is expected to pay a dividend of $3 in the upcoming year while stock y is expected to pay a dividend of $4 in the upcoming year. The expected growth rate of dividends for both stocks is 7%. The intrinsic value of stock x.
Based on the information given, the intrinsic value of stock x will be less than the intrinsic value of stock Y.
Based on the information given above, the intrinsic value of Stock X will be calculated thus:
D1 = Dividend in next year = $3
g = growth rate = 7%
r = = 13%
Therefore, intrinsic value of Stock X will be:
= D1 / (r-g)
= 3 / (13% - 7%)
= 3/6%
= 3 / 0.06
= $50
Therefore, the intrinsic value of stock X is $50.
Intrinsic value of Stock Y will be calculated thus:
D1 = $4
g = 7%
r = 13%
Intrinsic value of Stock Y will be:
= D1 / (r-g)
= 4 / (13% - 7%)
= 4/6%
= 4 / 0.06
= 66.67
Intrinsic value of Stock Y is $66.67
Therefore, the intrinsic value of Stock X will be less than the intrinsic value of Stock Y.
